A new book that is highly critical of Islam is now the number one bestselling non-fiction book in Germany, selling well over 100,000 copies less than two weeks after its initial release.

The book, entitled Hostile Takeover: How Islam Impedes Progress and Threatens Society, is the latest from former Social Democrat (SPD) politician and former member of the Executive Board of the Deutsche Bundesbank, Thilo Sarrazin. Hostile Takeover now leads Der Spiegel‘s bestseller list for non-fiction.

Mr Sarrazin is no stranger to controversy in Germany, having already published a harsh criticism of the country’s multicultural experiment entitled Germany Abolishes Itself in 2010. He has also become a leading thinker in Germany’s new right, which is largely centred around the populist Alternative for Germany (AfD).

The new work by the former SPD politician has also seen its own share of problems, having originally been picked up by publisher Random House which decided earlier this year they did not want to release the book. The move forced Sarrazin to take Random House to court and publish the book with FinanzBuch Verlag, instead.
